Correct Answer: C

Rationale: The correct answer is C: Increased breath sounds. When a client with pneumonia is receiving antibiotic therapy, increased breath sounds indicate that the lungs are clearing and the pneumonia is resolving. This improvement in breath sounds suggests that the antibiotics are effectively treating the infection. Choices A, B, and D are incorrect because a decreased white blood cell count, decreased respiratory rate, and increased heart rate are not specific indicators of the effectiveness of antibiotic therapy in treating pneumonia. While these parameters may change in response to treatment, they do not directly reflect the resolution of the pneumonia infection.

Correct Answer: B

Rationale: The correct first action for the LPN to take when a desired outcome is not achieved is to note which actions were not implemented. This step helps in identifying gaps in the plan of care and reasons for not achieving the desired outcome. Establishing a new nursing diagnosis (Choice A) is not the initial step when evaluating the plan of care. Adding additional nursing orders (Choice C) may not address the root cause of the unachieved outcome. Collaborating with the healthcare provider (Choice D) should come after identifying the gaps in the plan and reasons for the outcome not being met.

Correct Answer: A

Rationale: Encouraging the client to use the incentive spirometer 4-5 times per hour is the correct approach post-gallbladder surgery under general anesthesia. This frequency helps prevent respiratory complications, such as atelectasis, by promoting lung expansion. Choices B, C, and D suggest either too few or too many sessions per hour, which may not be optimal for the client's respiratory recovery needs. It is important to strike a balance between ensuring adequate lung expansion and not overexerting the client, which is why 4-5 times per hour is the recommended frequency.

Correct Answer: C

Rationale: The correct answer is C, 'Makes the moral judgment that 'stealing is wrong''. This finding signifies the attainment of the concrete operational stage according to Piaget. At this stage, children begin to understand rules and logic, including moral judgments. Choice A is incorrect because it does not specifically relate to concrete operational thinking. Choice B is incorrect as it refers more to the preoperational stage where children engage in symbolic thought. Choice D is also incorrect as it involves practical reasoning, which is not directly related to the concrete operational stage according to Piaget.

Correct Answer: A

Rationale: The correct first action for the nurse to take is to check the IV tubing for obstruction. This step is crucial in ensuring that the IV fluids are flowing properly and that there are no blockages preventing the correct infusion rate. Increasing the flow rate (Choice B) without confirming the tubing's status could lead to potential complications if there is indeed an obstruction. Changing the IV site (Choice C) is not the priority in this situation unless there are specific clinical indications. Notifying the physician (Choice D) can be done after checking the tubing for obstruction, as the physician may need to be informed depending on the findings.
